" 4 Application filed September 10, 1883. (No model.)

To tlliwhom il? may concern:

Be it known that I, HENRY W. EAsTMAN,

\ of the city of Baltimore, and State of Mary- `whereby ventilation may be had withoutdestroying the privacy of the chamber or admitting thereto 1nosquitoes,1iies, and other insects.

rIhe said invention consists in providing a door with a slatted aperture, over which is placed a screen of wire-work or other material which will admit ofthe free passage of air to and from the chamber, but at the same time intercept iiies and mosquitoes, and one ormore imperforate doors tocover the screen and thoroughly close the opening, as will hereindoors open.

after fully appear. t, t

In the accompanying drawings, forming a part hereof, Figure I is a vertical section of the improved door. Fig. II is a view of the outside of the door. Fig. III is a view ofthe inside of the door, or as it appears from the chamber, and With one of the imperforate l Figs. IV, V, VI, and VII illustrate modifications in t the construction of the slats, as hereinafter described.

SimilarI letters of reference indicate similar parts in all the views.

A is the chamber-door having an opening through it, which is here shown as ot' a size corresponding to the two upper panels and the bar between them.

B B are fixed slats, arranged to give free passage for air to and from the apartment without destroying its privacy. Where-the door A opens-`on a corridor or public passage the slats B may be of the ordinary inclined description, which prevents inspection of anyl -thing within the apartment, but allows persons within the chamber to distinguish objects in the corridor or passage, but as this door is designed in many cases as a communicating both has to be maintained. Itherefore employ slats with a double incline, as shown in the various figures of the drawings, In Figs. I, II, and III the slats are represented as formed of sheet metal with flat sides and the edges wired. In Fig. IV curved metallic slats are shown, while those in Figs. V. and VI are made of Wood and without the Wired edge. In Fig. VII the slats are of sheet metal and their rigidity increased by means of flanges a instead of wires.

C is a screen of iine-wire work placed over the inner edge of the slats B, to prevent entrance to the room of insects.

D D are folding imperforate doors, made to represent ordinary panels hinged within the aperture of the door, and adapted to be closed on or against the wire screen C.

It will be understood that when the imperforate doors D D are open there is free access of air to and from the apartment, but the privacy of the chamber is not destroyed or insects admitted thereto.

In applying this inventionto doo-rs non7 in use the upper panels and the bar between Y them'V are removed, and the slats, screen, and` imperforate doors substituted for them.

I claim as myinvention- 1. A Ventilating-door having a slatted opening, and one or more imperforate doors adapted to close the said opening, substantially as speci- 2. Aventilating-door having a slatted opening covered Witha screen, and one or more imperforate doors adapted to close the said opening, all combined substantially as specified. Y x
